Still, no matter what we do, in some cases audio will not work as expected, will miss refills, and there's nothing we can do about it. What we can do, however, is give the proper tools to handle these situations, including main thread audio processing that doesn't have to resort to manually transferring audio to a worker (or graphics to the main thread either), because that's even more expensive and likely to fail.
